LOOK.

Original application filed June 3, 1921, Serial No. 474,681. Divided and this application filed December 23, 1922. Serial No. 608,787.

To all whom it may concern:

Be it known that I, TVILLIAM F. KRAUT- 'lER, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Locks, of which the following is afull, clear, concise,and exact description.

My invention relates to looks, .being a division of my original application Serial No. 474,681, filed June 3, 1921.

The lock of my invention, and forming the subject matter of the present application, comprises the bolt thereof, a spring for pressing the bolt into locking position, a key actuated bolt withdrawing member serving, in one adjustment, to place the bolt in unlocking position and, in an alternative adjustment, adjusting said spring to function, a restraining member for holding the bolt in withdrawn position against the force of said spring when the key actuated memher is adjusted to place said springin bolt locking adjustment, and a detent for holding the restraining member in functioning position, said detent being withdrawable from its functioning position to permit said spring to place the bolt in locking position,

said restraining member being movable,

when the detent is withdrawn, by said spring into holding engagement with the detent to prevent the return of the detent to functioning position, said key actuated member having restoring engagement-with the restraining memberwhen the key actuated member is adjusted to place the bolt in unlocking position; By this arrangement the spring may be adjusted to a functioning condition in which it is maintained until the part of the lock which is com plemental to the bolt is placed in position to receive the bolt and all without per-.

initting the detent to assume functioning position irrespective of the relative positions of the bolt and the member of the lock complemental thereto. The lock is an improvement upon the type of lock disclosed in the patent to Samuel L. Terry, 1,206,944, dated December 5, 1916, and disclosing a lock for locking steering posts of automobiles. In the Terry look there is no restraining memher to hold the detent in non-functioning position while the steering post is being turned to bring a socketed portion thereof a into register with the locking bolt. my

construction the detent cannot assume a functioning position while the steering post or other element that is to be locked is being moved to bring the socketed portion thereof into register with the locking bolt.

I will explain my invention more fully by reference to the accompanying drawings showing the preferred embodiment thereof and in which Fig. 1 is a sectional plan view of the look as employed in association with the steering post and column of an automobile; Fig. 2 is a sectional view on line 2-2 of Fig. 1; Fig. 3 is a view similar to Fig. 1

showing some of the parts in another adj ustment; Fig. 4 1s a sectional view on line 4E 1 of Fig. 1; Fig. 5 1s a view generally similar to Fig. 1 but showing parts in figures.

The lock of my invention is shown in as sociation with the stationary steering column 1 and the rotatable steering post 2 of an automobile. The casing of the *lock is clamped upon the stationary steering column, andin order that it may be readily applied thereto, the casing is formed into two sections 3.and 1. The casing'section 3 is formed with a recess 5 thatis margined by a lip 6. The casing section 4 is formed with a 1i) 7 that interengages with the lip 6 when tie casing sections are assembled. A dowel pin 8 is at the other end of the casing and takes part in maintaining the casing sections in proper relation when the casing is closed. Screws 9 are freely slipped through the casing section 3 into threaded connection with the casing section 4. The

portions of these screws that do not extend into the casing section 4 are formed with annular channels 10 in their sides. A locking member 11 is formed with a slot 12 that receives a pin 13 eccentrically disposed upon a key actuatedcylindrical element 14, this key actuated element being mounted in the casing section 1 and constructed in any suitable way'to provide key controlled means whereby the element 14 may only be turned in response to the operation ofa key 15,

and as suclrlrey controlled: means forms-no novelpart of my present invention and may have a variety of embodiments, it will not be further described. The element ll is thus, itself, in the nature of a bolt and is formed with flanges 16 that enter the screw channels when the parts of the casing are to be locked together so that the screws '9 may not then be turned to efiecttheir to withdrawal.

lVhen the parts of the casing are to be n nlo'ckedto permit of their separation the 'bolt:ll-iswithdrawn to remove its flanges 16 from the screw channels 10 to permit said liscrewsto be 'unsc rewed. he casing sections are l'urthe'r locked together by providing thereintwo recesses- 17-and 18 into'an'd out of at least one o't-i'vhich the corresponding flange 16-01" 19 uponthe bolt 11- is passed 2) when the-member L is turned to locking position or teen unlocking positiOn'respec- -tivel'y. Ribs'QO andQLare formedas a consequence of the formation of said recesses '17- and 18, "these ribs being respectively in the casing sections 3 and t. Portions 16 and i 19 of the bolt 11, when this bolt is thrown to a lo'cking'position, engage-the outer faces of said' ribs'to 'hold the sectionsof the casing together. iVhile the casing is preferably formed as described, I do not wish to be limitedto snch aconstruction, in carrying out the balance'of'n'iyinvention.

The belt proper or main bolt 22 is ar ranged to slide back: and forthwithin a holding sleeve 23' that issuitably assembled with the casing section 4 to which the sleeve is secured, by means of screws 2% passing through the strap 25 andfiinto the casing section e. Theboreofthe sleeve is in regi ter with anopening 26 formed in the rotatable steering post The screws 24: serve "to clarnpthe stationary steering column 1 .between the casing-sections and the strap 25, the screws supplementing the screws Q l'in this function.

A boltthrowing coiled spring 27' is held at its outer end iin. a recess in the lrcy actua ted bolt 11 and at its innerend engages the head 281113011 the outer end-ofthe main bolt 22. -Wl1en this spring 'isadjusted to :and is free to peri orm its function it presses -the main boltQQ inwardly to cause it" to enten the-opening 26- in the steering post 2 "when the steering-ip'ost is suitably. positioned 'as indicated in Fig-b. The-spring 1-527, inorder that itunay perform :its tunetionyisbodily inwardly adjusted by the hey "actuated member M when this member is turned-to lockingvp'osition by tl1e"key 15. If thisspring, having: beenbodily moved toward 'the steering post 2 by theainward 'movemento'f the bolt 11, is free to perform its function by other 'meehanism that is 'hereinafter to be set forth, it will throw the bolt'22into locking position and into indi 'rect engagement-with the inturned end ot the bolt withdrawing or positioning member 29 that is mounted upon the bolt 11 that is directlyactuated'by the elementlfil-npon the lrey actuated member let, this member thus being a key actuated member. \(hen the main bolt 22 is to be drawn from its locking position the other bolt 1] is turnw'l by the ke-y 15 whereuponthe-withdrawing; or positioning member 29 moves the bolt outwardly, the spring 27 then bodily moving with said withdrawing member 29 and the bolt 11, the spring notthen functioning. A restraining member '30 is interposed between the intnrn'ed-end of the lmyacluated withdrawing member 29 and the bolt head :58, this restraining membenholding the bolt .22 'in theontnvard position -in which it is placed by the withdrawing memberill) when i the restrainingmember itseltis held as'wvill be' described. The restraining' inen'iber is held in its functioningposition by a dctent 31. ii coiled spring SQserves to place the detent-31"in position to hold the restraining member 30 when the-bolt has been withdrawn to its outer-or =unlocl in position, =the restraining member 3O being also 'wvithdrawn' to its outwardposition at the same time by the key actuated member The spring eti ecte d moi 'ement of the detent l1' i-s'desirably'limited by the projection 30 formed-upon the restraining member 30. lVhen"the restraining-member 30 isheld by the dctent-31 in functioning positionfthe -locking-member l l unay'be turned to -locking positionsas'illustrated in Fig. P, with-- out permitting" the spring 27' to function, the spring 'then bell-lg" placed-under .in creased "compression owingto the: fact that the bolt'll is force'd' towa'rdtheheld bolt 12s. The keyk'lfiflmay then-be withdrawn ihom the loclc and n'eed not again be inserted V *inorder' that the-main boltflil may be placed in locking position "*as I have provided zmeanswhereby theLdetentBlwmay 'bewith drawn fromlengagement with the restrain inginember 3O-to perinit the-spring 27 to *distend atrom its compressed 5 adjustment shown zin' Fig. 3 to its distended -form-shown zin 'Fi 5, the spring 27, when thus released,

alone serving to place the bolt 22 in"closed 'position nntlmut the-"aid' o'l the 'key. In orden thatthe' detent 31 may be released so that the-spring '27 maywplace'the bolt 22 i in lockingi-position, Iunon-nt "said delent wnpon a'rod that is-slidably mounted in the casing section 4l-,i' this red "having a knurled ahead 3 l-uipo1rthe exterior of said ca-sing se'ctionwherebythe rod may be pulled out- Wvardly to movehthe"detent 31 outwardly froin the position shown-in Fig. 3 against the force of themletent spring 32-into the position shown in 5.

Itewill be observed thatlthe restraining vrnernber, by engaging the withdrawn detent, prevents this detent from auto1natically assuminga functioning position while the steering post is being turned .to bring the opening or socket 26 thereof into register with the bolt. If it were not for this rcstraining member the detent would have to be held in a withdrawn position byhand while the steering post is being turned into locking position. Because of the presence of the restraining member it is simply necessary to withdraw the detent which is automatically held in its withdrawn position by the restraining member while the bolt is riding upon the smooth portion of the steering post as the latter is being turned to bring its opening 26 into register with the bolt.

While I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention, but having thus described my invention I claim as new and desire to secure by Letters Patent the following 1. In a lock, the combination with the bolt thereof; of a spring for pressing the bolt into locking position; a key actuated bolt withdrawing member serving, in one adjustment, to place the bolt in unlocking position and, in an alternative adjustment, adjusting said spring to function; a restraining member for holding the bolt in withdrawn position against the force of said spring when the key actuated member is adjusted to place said spring in bolt locking adjustment; a detent for holding the restraining member in functioning position; and a spring for holding the detent in functioning position, said detent being withdrawable from its functioning position in opposition to said latter spring to permit the first aforesaid spring to place the bolt in looking position, said restrainingmember beingmovable, when the detent is withdrawn, by the first aforesaid spring into holding engagement with the detent to prevent the return of the detent to functioning position said key actuated member having restoring engagement with the restraining member when the key actuated member is adjusted to place the bolt in unlocking position.

2. In a lock, the combination with the bolt thereof; of a spring for pressing the bolt into locking position; a key actuated bolt withdrawing member serving, in one adjustment, to place the bolt in unlocking position and, in an alternative adjustment, adjusting said spring to function; a restraining memberfor holding the bolt in withdrawn position against the force of said spring when the key actuated member is adjusted to place said spring in bolt locking adjustment; and a detent for holding the restraining member in functioning position, said detent being withdrawable from its functioning position to permit said spring to place the bolt in locking position, said restraining member being movable, when the detent is withdrawn, by said spring into holding engagement with the detent to prevent the return of the detent to functioning position, said key actuated member having restoring engagement with the restraining member when the key actuated member is adjusted to place the bolt in unlocking position.

In witness whereof I hereunto subscribe my name this 6th day of February A. D. 1922.
